ProStereo™ D1 Professional Wireless Hi-Fi Headphone Amp + DAC works with any smartphone or computer. Smartphones and computers on their own do not always produce smooth sound – in fact, it’s often noticeably bad! Upgrade your music to studio quality! Accented with an eye-catching triangular prism design, this one further depicts a sturdy, circular charging dock to hold the device. Built of excellent workmanship, it expresses minimalism with a metallic and cool touch.
The Perfect Marriage of Smartphone and Headphone
ProStereo™ D1 Professional Wireless Hi-Fi Headphone Amp + DAC works with any smartphone or computer. Smartphones and computers on their own do not always produce smooth sound – in fact, it’s often noticeably bad! Upgrade your music to studio quality!
Here’s the truth:
Audio CDs use a bit depth of 16-bits, while DVD-Video and Blu-ray discs can use 24-bit audio.
ProStereo™ D1 has Hi-res audio certification from JAS with audio output of up to 32-bit / 384 kHz.
A Total Solution of Hi-Fi Audio Experience
To deliver the best quality of music enjoyment, ProStereo™ D1 bundled with a pair of High-Res Audio Headphones with a 5Hz – 70 kHz high-frequency range produces smooth bass sounds.
How It Works
ProStereo™ D1 supports the Sample Rate Converter, no matter which type of music file is playing on your mobile phone, or in USB DAC Mode (MP3, AAC, FLAC, etc.), the audio data can be raised up to 32-bit / 384 kHz and is processed by an independent Hi-Fi DAC.
Extraordinary USB DAC With High-Resolution Audio
ProStereo™ D1 can be used as a professional external USB DAC by connecting the USB cable to your devices and external accessories (phone, mp3 player, or computer).
High-Resolution Audio Earphones Included
The ProStereo™ D1 comes with earphones that are fully compliant with the Hi-Res Audio requirements set by the Japan Audio Society. You will notice a clear and fine sound output in wide treble performance and a solid, deep bass due to a frequency rate of up to 70 kHz. There is also a 9mm dynamic driver to allow for a sense of natural sound clarity.
